Grass can grow pretty fast, depending on certain details. Lawns look their very best when they are mowed short.
A very good idea would be to plant grass which grows more slowly and still apply an organic fertilizer. These types of grass are usually quite resistant to drought or other harsh conditions. By planting this type of grass you can save a lot of money, energy and time. Among these slow-growing grasses we could mention clover, Fescues, Buffalo grass, etc.
Another good idea may be using plant growth inhibitors. They should be applied thoroughly on your lawn, and this may also take time. This must ensure the fact that you do not miss any plant while spraying.
In case your lawn is growing too fast, chances are you are giving it too much care and attention. In other words, you may consider reducing the amount of water and fertilizer you are using for your lawn.
It is an interesting fact that in many parts of the country grass tends to go dormant during the hot season. Although lawns which are properly taken care of look great, they certainly require a lot of care and regular maintenance.
Using artificial turfs may be another solution in case you are worried about the speed at which your grass is growing.
